Default Fabricating a larger collector on to a header?

I have an h22a and it currently has a dc sports header 4-2-1 with a 2.25 in collector. Dc sports makes another header with a 2.5in collector but could I custom fabricate my current header to make a 2.5in collector by cutting off closer to the meeting point of the 2-1 and welding a pipe straight from there?
Thanks!

What size are your primaries?

I believe that they're 1 5/8 primaries and 2.25 final collector.
